What it means is all plays are on tape and there's no hiding whether a player is playing well or not. The game film doesn't offer excuses or conditions -- just reality.

Television cameras don't lie, either. During Sunday's 32-20 loss by the Detroit Lions to the Seattle Seahawks, there was an interesting clip from the Detroit sidelines at Qwest Field.

Lions rookie quarterback Matthew Stafford can be seen talking to receiver Calvin Johnson, who was seated on a bench on the sideline. It appears that Johnson wasn't happy with what Stafford had to say because Johnson turned away, ignoring him.

On Monday, Johnson did not deny the incident happened, but he did his best to downplay it.

"Frustrated with the loss. If we win, all of that's out the window," Johnson said. "There's no problem with us. People are just blowing it out of proportion."

Exactly what Stafford said isn't known. Stafford was not available for comment Monday.

Stafford and Johnson had reasons to be frustrated. Not only did the Lions blow a 17-0 first-quarter lead, Stafford threw five interceptions and Johnson wasn't much of a factor, catching just two passes for 29 yards.

The Lions are 1-7 at the halfway point of this season and own the NFL's longest current losing streak (five games). Detroit has lost 16 consecutive games on the road and travels to Minnesota, where the Lions have lost 11 in a row. Overall, the Lions have lost 30 of their past 32 games.

"It's been awhile now since I've been here. We haven't gotten enough wins, and it's definitely frustrating," Johnson said. "Nobody's going to be happy about that. There's something wrong if you are."

The sideline situation apparently was serious enough for Lions coach Jim Schwartz to investigate and discuss it with Stafford and Johnson.

"There's no issue there. I've talked to the players," said Schwartz, adding sideline disputes between players is a natural occurrence in the NFL. "Good gracious, if there was a camera on every single person on every single play, you could read between the lines on a million different things.

"You want to be happy and cheerful and you want to win football games, and there are things that you have to work through. There are going to be times that you need to talk things out and stuff like that. I don't even see it as being an issue. I know it's not for the players, and I don't understand why somebody would make an issue, when it's not even an issue."

Injuries could be an issue for the Lions as linebacker Ernie Sims had more tests on his injured hamstring Monday. Schwartz indicated there's the "potential" that Sims could miss some time.

"I just tweaked my hamstring. I'm going to the hospital to get more tests done," Sims said. "I've never had a hamstring injury before so I'm just hoping it's not that bad so I can get back on the field."

The Lions got more encouraging news on the right leg injury to rookie safety Louis Delmas; Schwartz described his injury as "short term."

"I'm feeling good. I think it scared me more than anything. It wasn't as serious as I made it," Delmas said.
